Ross D. Franklin / APOlympic gold medalist in women's beach volleyball at the 2008 Beijing Olympics Misty May-Treanor throws out the first pitch prior to the Florida Marlins baseball game against the Arizona Diamondbacks Sunday, Aug. 24, 2008, in Phoenix.

Susan Lucci, Toni Braxton and Lance Bass will hit the floor on ABC's "Dancing With the Stars."

They are among 13 celebrities slated to compete on the new season of the top-rated dance contest, premiering Sept. 22.

The other contestants are Cloris Leachman, Kim Kardashian, Ted McGinley, Brooke Burke, NFL champ Warren Sapp and two Olympic athletes: Misty May-Treanor, who won her second gold medal for beach volleyball at this year's summer games in Beijing, and Maurice Greene, who won two gold medals in track at the 2000 games in Sydney.

Kardashian, who co-stars with her family on the E! reality series "Keeping Up With the Kardashians," checked into a New York City hospital Sunday after cutting her foot on a glass table in her hotel room.

"I will be able to dance. I went to the hospital. I'll be fine," she said in a phone call to "GMA."
